Halff Ranch occupies a central position in this Frio County landscape, where the seasonal hydrology of the South Texas brush country is clearly defined. The area is dominated by the winding course of the Frio River, which is fed by numerous tributaries including Buck Cr, Hondo Cr, and Live Oak Cr. This 2019 survey documents a landscape heavily managed for water, featuring several named man-made reservoirs such as Salt Hollow Tank, Javelin Tank, and Hog Tank.
